Just watched Kurt the Cyberguy tell people to copy and paste coupon codes as opposed to clicking the link. It sounded to me like he was saying not to click on the link to prevent the owner of the site who brought you the code earning some money as an affiliate of the advertiser.
I say copy the code and click the link. Somtimes the best deal is available by clicking the link and then pasting in the promo code.
Also use promo code + advertiser to save money.
Like with DVDPlay you can get free rentals of top movies by using the codes. The latest codes for DVDPlay are:

With this site you take the code with you and input it at the kiosk and get a movie. Just be sure to return it before 7pm the next day, or you will pay for the extra day!
